U2 singer Bono has been showing off his best American drawl as he impersonated for Bill Clinton.
As he waited for the former US president on stage at the Clinton Global Initiative in New York, Bono began a striking impersonation of Mr Clinton.
To the obvious delight of the audience the U2 frontman described how Clinton "thought he was one his roadies" the first time they met before listing their humanitarian achievements.
When Mr Clinton did arrive the Irish singer leapt back in to his own seat as the former president said he "must be really easy to make fun of."
Bono filled in for Bill Clinton at a meeting of heads of state and business leaders - by jumping into the former US President's chair and doing an impression of him.

Irish rock star Bono has been awarded the highest cultural honour of France, and was praised for waging "some of the greatest wars of our time."
The U2 front man was presented the Commander of the Order of Arts and Letters by French minister of culture Aurelie Filippetti, in a ceremony in Paris. Filippetti said:
"Beyond notes and beyond words, you committed yourself and dedicated your fame and career to wage some of the greatest wars of our time. Not for charity's sake but in the name of Justice."
Accepting the award, Bono said he was hugely honoured by the accolade, but that it belonged to the band:
"This is a huge honour for me, but really it belongs to the band. I've got the biggest mouth and the loudest voice but the music we make comes from each other, [...] it is unspeakably special to receive an award from France for being an artist."
